HOT AIR DUCTING INSTALLATION
The Brentwood™ fireplace is approved for use
with a Gravity Kit.
Gravity Kit
The gravity kit is designed for double hot air out-
lets and includes: (See Figures 12 and 13)
- 2 telescopic lengths 8” I.D.
- 2 90º elbows 8” I.D.
- 2 hot air outlet kits (grill and frames)
- 2 adaptors
See Gravity Kit Accessories on Page 21.
The only blower that can be used with the gravity
kit is the UZY5.
The gravity kit allows you to block the upper
louver of the fireplace. To do so, follow the
steps below:
a) Remove the upper louver from the fire-
place.
b) Install the black panel (BWCF) making sure
that the insulation strip is installed inside.
c) The fireplace facade can be covered with
non-combustible material (Figure 14).
For safe installation, the gravity kit must meet
the following requirements:
Minimum height* 68” (1,727 mm)
Maximum length See
Figures 13 and 14
* The height of the louver must be measured
from the base of the Brentwood fireplace to the
middle point of the louver.
To extend the double outlet system forward of
the Brentwood fireplace (not flush), it will be
necessary to purchase two adjustable lengths
(7B26ZL2A).
When installing the double outlet system, the
hot air outlets can be installed in the same room
as the fireplace, or one or both of the outlets
can be installed in adjacent or upper rooms.
Installing the ducts at different elevations will
tend to exhaust more heat out of the higher
outlet (Figure 13).

er installation may cause
fire and void warranty.
